Add's a countour to the missing animal posters on Heat Streat Heist.
Install it in mod_overrides folder.

The mod has 2 bugs that probably are unfixable, they are:
1 - The poster will only be highlighted if the player is facing it frontside, this bug may happen because the poster has no visible backside.
2 - The missing animals posters gets yellow highlights, but due to the texture file be the same as the one used by other props, some signs and random posters may also be highlighted but in white, just ignore them.
